Al2O3 Bulletproof Ceramic Phaj

Cov mos txwv, cov khoom tawg, stabbing nrog cov khoom ntse - niaj hnub no cov kws tshaj lij uas muaj kev pheej hmoo siab yuav tsum tau tawm tsam nrog ntau qhov kev hem thawj ntau ntxiv. Thiab nws tsis yog tub rog thiab tub ceev xwm nkaus xwb uas xav tau kev tiv thaiv. Nyob ib ncig ntawm lub ntiaj teb no, cov neeg saib xyuas hauv tsev loj cuj, cov neeg nqa nyiaj ntsuab thiab cov neeg ntiag tug txhua tus tau muab lawv lub neej rau ntawm txoj kab rau lwm tus neeg txoj kev nyab xeeb. Thiab lawv txhua tus tsim nyog tau txais kev tiv thaiv thawj zaug. Txawm hais tias ib puag ncig, txawm tias muaj kev hem thawj, peb cov ntaub ntawv tau tsim nrog ib lub hom phiaj: ua kom muaj kev nyab xeeb zoo tshaj plaws. Nrog peb cov khoom siv ballistic tshiab thiab cov kev daws teeb meem, peb pab xa cov kev tiv thaiv zoo rau cov neeg siv. Ib hnub dhau ib hnub, xyoo dhau xyoo. Lub caij no, peb tseem tab tom teeb tsa cov qauv tshiab rau stab- thiab spike-tiv thaiv cov khoom - nrog cov ntaub ntawv uas muaj kev sib tw tsis sib xws thiab txiav tsis kam. Tag nrho thaum txo qhov hnyav. Tag nrho thaum nce kev nplij siab thiab ua kom muaj kev ywj pheej ntawm kev txav mus los. Koj tuaj yeem paub tseeb txog qhov ntawd.

Xws li daim hlau ntawm cov tuab tuab feem ntau yog ua los ntawm axial nias kom zoo. Nyob rau hauv cov ntaub ntawv ntawm alumina thiab silicon carbide hexagons, lub bevel yuav raug tsim thaum lub sij hawm shaping txheej txheem los yog tom qab sib tsoo. Cov khoom yuav tsum tau zoo kawg nkaus tiaj tus thiab nyob rau hauv nqaim dimension tolerances kom txo tau machining zog. Lawv kuj yuav tsum tau ntom ntom, vim qhov porosity sab hauv yuav txo qis hardness, nruj thiab ballistic kev ua tau zoo. Inhomogeneous ntsuab ntom ntawm qhov chaw mus rau qhov chaw ntawm qhov nias yuav ua rau warping los yog inhomogeneous ntom tom qab sintering. Yog li, qhov yuav tsum tau ua rau qhov zoo ntawm cov pressed ntsuab lub cev yog siab. Txhawm rau tshem tawm cov porosity seem, cov ntaub ntawv zoo li no feem ntau tom qab HIPed tom qab cov pa sintering. Lwm cov txheej txheem tsim khoom kuj tseem siv tau tab sis yuav tsis muaj kev lag luam sib tw rau kev tsim khoom loj los ntawm axial nias.
